  1. ap < 0.001, bp < 0.01, cp < 0.05, dp approached the significance < 0.05. CD4 count < 200 cells/mL was not included because it was insignificantly associated with mental health summary scores (p = 0.407). Years since starting ART was excluded because of co-linearity with the variable, years since HIV diagnosis. *Further multivariable linear regression models were performed for each basic need, estimated coefficient (β) unmet needs: food = −4.10, clothing = −3.39, housing cost = −4.34 or risk of homelessness = −3.07 (all, p < 0.001)
